Title: Innovations and Contributions of John A. Dahlquist
Introduction
John A. Dahlquist, based in Palo Alto, CA, is an inventor with a significant portfolio of ten patents. His work has primarily focused on advancing coating technology, particularly in the development of systems and methods for evaluating and managing coating processes.
Latest Patents
One of John A. Dahlquist's latest innovations is the "Gel Point Sensor," which employs a method of analyzing the specular and diffused radiation reflected from coatings. This system allows users to locate the gel point of the coating and monitor its drying characteristics, ultimately enhancing the optimization of coating quality and mill efficiency. The method involves illuminating a specified area of the coating with a radiation source and using two distinct radiation detectors. One detector captures specular radiation, while the other collects only diffused radiation. The ratio of these readings provides critical information regarding the gel point location and the drying characteristics of the coating.
Additionally, Dahlquist has developed a "Coating Weight Measuring and Control Apparatus and Method." This invention outlines a sensor and methodology for determining the basis weight of coating materials—specifically those containing calcium carbonate (CaCO3)—applied to substrates. This innovation ensures that the basis weight remains consistent, regardless of variations in the underlying substrate material, allowing for better control in achieving a uniform coating.
